Question

derive prism formula when refraction of light take place trough a glass prism.​

Answer 1

Explanation:

Refraction is the bending of light when it goes from one medium to another so, when a ray of light passes through a glass prism, refraction of light occurs both, when it enters the prism as well as when it leaves the prism. In this case the ray of light is deviated on passing through the prism.
